What type of harness must be worn when working from an aerial lift?

When working from an aerial lift, it is essential to wear a full body harness with a 6' deceleration lanyard. This type of harness is designed to provide comprehensive support and safety for the worker during operations at height.

A full body harness distributes the forces experienced during a fall across all parts of the body, which helps to minimize injury. It is crucial for maintaining the worker's position in the lift and preventing them from falling out. The inclusion of a deceleration lanyard, typically around 6 feet in length, ensures that, in the event of a fall, the worker is safely arrested and brought to a stop within a controlled distance.

Other types of harnesses, such as a chest harness, waist harness, or back support harness, do not offer the same level of protection and support needed when working at heights, particularly in aerial lifts. They lack the appropriate design to prevent falls effectively and manage the forces exerted on the body during an incident, making them unsuitable choices for this type of job. Therefore, the combination of a full body harness and a deceleration lanyard is the only option that meets the safety requirements for workers operating from an aerial lift.
